The present invention relates to an elliptical machine, and more particularly to an innovative structure wherein the lateral movement of the pedal can be freely controlled according to the user's force application mode.
Because of the busy life in modern days, most people feel very tired when they get home, not having spare energy to exercise. After the rise of leisure and health, the concept of physical fitness has become popular. However, finding the suitable place for sports is another problem for people who want to exercise. In terms of the popular choices of school playgrounds and parks, although they are convenient and free, they are easily affected by the weather and cannot be exercised. In view of this, the sports equipment industry has developed a variety of sports and fitness devices that are convenient for indoor use, so that the users can utilize spare time and achieve indoor exercise and fitness.
In the wide range of sports equipment, because the running trajectory of the elliptical machine pedal can simulate the movement trajectory of the foot and the leg when walking, it is more ergonomic, so it is favored by many consumers. However, the running trajectory of the two pedals of the currently commercial available elliptical machine is limited to two planes parallel to each other, so that the part of the exercise is fixed, and the corresponding relationship between the two pedal movement trajectories cannot be changed according to different force applying modes of the user.
The present invention mainly aims to provide an elliptical machine with function of freely controlling the lateral movement of the pedal, and the technical problem to be solved is to how to develop a more ideal and practical new elliptical machine structure which the lateral movement of the pedal can be freely controlled, it is an innovative breakthrough as the goal.
The technical feature of the present invention is mainly to solve the problem that the elliptical machine comprises: a base, which is in a forward-backward extension and comprises a front frame part and a rear frame part, and virtualizes a forward and backward axis as well as a side axis according to the base type; an upright column is fixed on the front frame part of the base; a transmission mechanism is mounted on the front frame part of the base, the transmission mechanism comprises a bracket and a flywheel screwed on the bracket by a rotating shaft, and two ends of the rotating shaft are respectively fixed with a crank, each crank has a free end part, and the free end part is fixed with a pivot; two lateral swing tracks are respectively disposed on the rear frame part of the base in the left and right interval arrangement relationship. Each lateral swing track comprises a pivot end and a swing section. The pivot end is pivoted at a fixed position of the rear frame part, and the swing section extends a length along the anteroposterior axis, so that the swing section is in a displaceable state on the rear frame part, and forms that when the swing section is controlled by an external force, it takes the pivot end as a pivot point, and it is in a left and right lateral arc track freely-swinging state along the lateral axis direction; and a pair of connecting rod and stepping mechanisms. Each of the pair of connecting rod and the stepping mechanisms are disposed on corresponding sides of the transmission mechanism, and both are in a mutually interlocking relationship. Each connecting rod and the stepping mechanism comprises a front connecting rod, its bottom end is pivoted to the base, and one side of the front connecting rod body is pivoted to the corresponding pivot disposed by the crank; a rear connecting rod, its front end is connected to the rear end of the front connecting rod in a universal transmission type, and the rear end of the rear connecting rod is disposed on the corresponding lateral swing track; a pedal with a screwing particular for being screwed to a corresponding rear end part of a rear connecting rod, which forms that the pedal takes the screwing part as a pivot point in a rotatable state by force, and the pedal group is provided with an angle suppression limit device, so that the rotation of the pedal can be limited to a set angle range.
With said structural composition and technical features, when the user steps on each pedal, the flywheel is driven by each front connecting rod, and the front connecting rod is reciprocally extended with the rotation angle of the flywheel and the crank, thereby causing the movement of each pedal in the elliptical trajectory, and the user can selectively apply the lateral force on the pedal through the feet, freely and separately to manipulate the swing section of the lateral swing track in the left and right lateral arc track swing, thereby greatly improving the action type and exercise fitness effect of the elliptical machine to use, so as to meet the practical progress of multiple needs.

Each lateral swing track 40 comprises a pivot end 401 and a swing section 402, wherein the pivot end 401 is pivoted in a fixed position of the rear frame part 12, the swing section 402 extends a length along the front-rear axis L1, so that the swing section 402 is placed on the rear frame part 12 in a displaceable state. When the swing section 402 is controlled by an external force, the pivot end 401 is used as a pivot point, it is in the leftward and rightward arc track free swing state; a pair of connecting rod and stepping mechanisms 50 disposed on one corresponding sides of the transmission mechanism 30, so that both are interlocked with each other; each of the pair of connecting rod and stepping mechanisms 50 comprise: a front connecting rod 51, the bottom end is pivotally disposed on the base 10, the rod body side of the front connecting rod 51 is pivotally disposed on the corresponding pivot 34 in the crank 33; a rear connecting rod 52, the front end is connected to the rear end of the front connecting rod 51 in universal transmission type; the rear connecting rod 52, the rear end is disposed on the corresponding lateral swing track 40; a pedal 53, the pedal 53 has a joint part 531 for being screwed on the rear end part of the corresponding rear connecting rod 52, so that the pedal 53 takes the joint part 531 as a pivot point in the forced rotation state, and the pedal 53 is provided with an angle suppression limit device 54 for setting the rotation inhibition limit of the pedal 53 within a set angle range.
Preferably, the front connecting rod 51 comprises a first long member 511 and a second long member 512. The first long member 511 and the second long member 512 are axially combined with each other in a retractable state. The bottom end of the first long member 511 is pivoted at the base 10; one side of the second long member 512 is pivotally disposed on the pivot 34 corresponding to the crank 33, and the second long member 512 is axially reciprocated relative to the first long member 511 when the crank 33 is rotated, thereby changing the length of the front connecting rod 51, and the rear connecting rod 52 is connected to the rear end of the second long member 512.
